CROSS-REFERENCE TO RELATED APPLICATIONS
The present application claims the priority benefit of U.S. provisional application No. 61/989,402 filed May 6, 2014 and entitled “Integral Spring Bottom Metal Latch,” the disclosure of which is incorporated herein by reference.
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention generally relates to gunstock floor plates. More specifically, the present invention relates to the release of a floor plate or magazine in the bottom metal assembly of a gunstock floor plate.
Description of the Related Art
The gunstock of a rifle is that part of the rifle to which to which the barrel and firing mechanism are attached. Also coupled to or integrated with the stock is the floor plate. Floor plates are well known in the art and operate to close the bottom of the magazine recess in a bolt-action rifle having a clip-loaded magazine.
One type of floor plate is the hinged floor plate. A hinged floor plate is a floor plate that swings open but remains attached to the rifle such as might be found in a Remington 700 rifle. Cartridges are loaded with the bolt in the open position and pushed down into the magazine-well area of the stock. To unload the cartridges, a switch or button located by the trigger is actuated to allow the bottom of the action to open and dispense unused cartridges.
Some rifle floor plate designs allow for a clip magazine to be mounted to a hinged floor plate. Cartridges are loaded into a clip that can be inserted into the stock and removed by actuating a switch or button as described above. Such a design is sometimes referred to as a drop box, a detachable magazine, or a detachable box magazine.
Recoil is the backward momentum of a rifle during discharge of a projectile. Recoil results when a rifle balances the forward momentum of a projectile and exhaust in accordance with Newton's Third Law of Motion (i.e., all forces exist in pairs). Rifles with hinged floor plates (or floor plates allowing for introduction of a drop box or detachable magazine) and that have heavy recoil will often cause the trigger finger of a shooter to unintentionally come into contact with the aforementioned switch or button of the floor plate. The heavy recoil of the rifle coupled with the unintentional contact results in actuation and a resulting opening of the action, which dispenses unused cartridges.
This unintentional recoil contact, actuation, and dispensing of cartridges or release of a drop box or clip can be an inconvenient annoyance. Cartridges or clips can be lost or damaged as a result of the unintentional and unwanted opening of the action. Collection and reinsertion of the unintentionally dispensed cartridges interrupts a shooting experience, which can lessen the enjoyment of the shooter or result in a missed shooting opportunity. Some shooters may, however, be involved in big game hunting (e.g., large game such as elephants or other African game). If the action opens and dispenses cartridges following ejection of a projectile, the now injured and unquestionably startled game could elect to attach the shooter causing severe injury—or death—as the shooter attempts to recollect and reintroduce unintentionally dispenses ammunition.
There is a need in the art to solve the problem of those rifles having hinged floor plates and heavy recoil from erroneously ejecting cartridges as a result of unintentional trigger finger contact following firing.
SUMMARY OF THE PRESENTLY CLAIMED INVENTION
In a first claimed embodiment, an integral spring bottom metal latch system is claimed. The system includes a latch body with a through hole and movement arm. The system further includes a spring that operates as resistance to release of a floor plate of magazine in a bottom metal assembly. A catch holds the floor plate or magazine in place.
An integral spring bottom metal latch system is also claimed in a second embodiment. The second claimed embodiment includes a bottom metal assembly and integral spring that operates as a primary resistance to the release of a floor plate in the bottom metal assembly.
A third claimed embodiment recites a further integral spring bottom metal latch system. The system includes a bottom metal assembly and integral spring that operates as a primary resistance to the release of a magazine in the bottom metal assembly.
BRIEF DESCRIPTION OF THE DRAWINGS
<figref idref="DRAWINGS">FIG. 1</figref> illustrates an integral spring bottom metal latch system in a rifle with a hinged floor plate.
<figref idref="DRAWINGS">FIG. 2</figref> illustrates an integral spring bottom metal latch system in a rifle with detachable box magazine system.
DETAILED DESCRIPTION
The integral spring bottom metal latch of the presently disclosed invention represents an improvement to prior art bottom metal latches and corresponding floor plate systems. The integral spring bottom metal latch of the presently disclosed invention includes a spring that operates as the primary resistance to the release of the floor plate or magazine in the bottom metal assembly. The bottom metal assembly is the trigger guard and magazine system in a bolt action rifle.
By integrating the spring into the metal latch assembly, the spring may exhibit higher strength than compression springs as found in prior art floor plate systems. The integrated spring, too, may be tooled and manufactured to address the specific recoil requirements of a specific rifle design. The presently disclosed integral spring bottom metal latch may be utilized in both a hinged floor plate and detachable box magazine design.
<figref idref="DRAWINGS">FIG. 1</figref> illustrates an integral spring bottom metal latch system <b>100</b> in a rifle with a hinged floor plate. The system <b>100</b> of <figref idref="DRAWINGS">FIG. 1</figref> includes a latch body <b>110</b> having a through hole and movement arm <b>120</b>. The system <b>100</b> of <figref idref="DRAWINGS">FIG. 1</figref> also includes exposed button <b>130</b> and a thin, webbed, integrated spring <b>140</b>. The spring may be curved, straight, tapered, or reverse tapered. The spring may be one piece or multiple components having different lengths and different tension. The spring may also be parallel or of a convex, or concave configuration. The spring may be integrated or attached to other components. In an alternative embodiment, the spring may be of a cantilever design. System <b>100</b> also includes a catch <b>150</b> that holds the floor plate <b>160</b> in place.
When the button <b>130</b> is pressed in system <b>100</b> of <figref idref="DRAWINGS">FIG. 1</figref>, the catch <b>150</b> is rotated about the through hole <b>120</b>. The rotation compresses the thin, webbed, integrated spring <b>140</b>. As a result of the aforementioned compression, the floor plate <b>160</b> is released thereby allowing shells to drop out. The design of the system <b>100</b> of <figref idref="DRAWINGS">FIG. 1</figref> prevents a rifle with a hinged floor plate and heavy recoil from allowing the trigger finger of a shooter to unintentionally come into contact with the switch or button allowing for release of the floor plate and erroneously releasing ammunition from the rifle.
<figref idref="DRAWINGS">FIG. 2</figref> illustrates an integral spring bottom metal latch system <b>200</b> in a rifle with detachable box magazine system. The system of <figref idref="DRAWINGS">FIG. 2</figref> is similar to the system <b>100</b> of <figref idref="DRAWINGS">FIG. 1</figref>. The system <b>200</b> of <figref idref="DRAWINGS">FIG. 2</figref> includes a latch body <b>210</b> having a through hole and movement arm <b>220</b>. The system <b>200</b> of <figref idref="DRAWINGS">FIG. 2</figref> also includes exposed button <b>230</b> and a thin, webbed, integrated spring <b>240</b>. The spring may be curved, straight, tapered, or reverse tapered. The spring may be one piece or multiple components having different lengths and different tension. The spring may also be parallel or of a convex, or concave configuration. The spring may be integrated or attached to other components. In an alternative embodiment, the spring may be of a cantilever design. System <b>200</b> also includes a catch <b>250</b> that holds the magazine <b>260</b> in place.
When the button <b>230</b> is pressed in system <b>200</b> of <figref idref="DRAWINGS">FIG. 1</figref>, the catch <b>250</b> is rotated about the through hole <b>220</b>. The rotation compresses the thin, webbed, integrated spring <b>240</b>. As a result of the aforementioned compression, the magazine <b>260</b> is released thereby allowing cartridges to drop out. The design of the system <b>200</b> of <figref idref="DRAWINGS">FIG. 2</figref> prevents a rifle with a hinged floor plate and heavy recoil from allowing the trigger finger of a shooter to unintentionally come into contact with the switch or button allowing for release of the magazine and erroneously releasing a cartridge from the rifle.
